What is OSI model? Before going into OSI model e ill learn hitory of networking. In history there were two companies whose computer were used i.e, DECnet solution and IBM solutions.   Suppose there is company who uses these two computers and they want to transfer data from DECnet to IBM computer then they don't support and information is not sent i.e, different computer having different operating system doesn't share information.  So to resolve this problem ISO(International Organization for Standardization) in 1984 developed OSI(Open System Interconnection) model based on layered approach. To understand the meaning of layered approach consider example, A company is divided into many department to continue smooth work.Like this to continue smooth communication different layers are defined for different purpose. o it is called layered approach.  In OSI model there are seven different layers . The main purpose of OSI model is how data and network information are communic...

Types of Network There are basically six types of network. 1.PAN(Personal area network) This type of network are used for personal level i.e, communication between laptop and mobile, laptop and tablet, computer and printer. PAN can transfer information in both wired and wireless form. The wired communication in PAN is formed through USB(Universal Serial Bus) Cable. The wireless communication is formed through bluetooth, hotspot etc.  PAN type of network basically used to send small size files such as music,images. The geographical area of this type of network is a single room. 2. LAN(Local Area Network) The computer network devices such as switches, server, Printer, Computer connected together located in a particular building are local area network. The cable used to connect LAN network is Ethernet cable connected to RJ45 connector. The design of LAN network is easy and the speed of LAN network is high. LAN is private type network. The geographical area of LAN Network is between 1 ...

What is a Network? A group of devices connected to eachother to share information is called as a basic network. What is a Computer Network? A group of computers and devices such as switch, router, printer and scanner connected to eachother to share information or data is called computer network. What is Topology? Topology is the way in which network communicate with different devices. Types of Network Topology Wired Topology The devices which are connected to eachother through a cable are called wired topology.    1.  Star Topology All devices connected to single device such as switch or hub to share data is called star topology.                                           Fig 1:- Star Topology Using Packet Tracer Software. As shown in above fig 1 four computers are connected to a single switch. Advantages   Other devices will not due to single device failure. Easy ...
